  • the communication within the network 8 can be accomplished by using at least two different communication standards.
  • the electronic devices 1, 1a to 1e can communicate according to a first communication standard and according to a second communication standard.
  • the electronic device 1 and the further electronic devices 1a to 1e each have a first address within the network 8 relating to the first communication standard and a second address within the network 8 relating to the second communication standard.
  • the first communication standard hereby is a slow connection having a slow bandwidth and the second communication standard is a fast connection having a high bandwidth.
  • the first communication standard is a communication according to the consumer electronics control (CEC) standard and the second communication standard is a communication based on an Ethernet connection.
  • the first interface 6 provides a HDMI connection having an additional CEC line.
  • the first interface 6 of the electronic device 1 hereby enables a communication according to the first communication standard and the second interface 7 of the electronic device enables a communication according to the second communication standard.
  • the advantages of the different used communication standards can be combined, so that for example a communication standard having a low bandwidth can use the other communication standard when the need arises to transmit large amounts of data.
  • the present invention further provides a possibility to administrate the addresses of each electronic device 1, 1a to 1e connected to the network 8 and using different communication standards.
  • the first communication standard is a communication standard relating to the consumer electronics control (CEC) standard and the second communication standard is related to a communication based on an Ethernet connection.
  • the first address is hereby a CEC logical address and the second address is an IP Ethernet address.
  • the present invention is not intended to be limited to the above types of communication standards but can be adapted to any other type of communication standard. Further, the present invention is not limited to the use of two different communication standards but can also adopt three or more communication standards. In this case in the electronic device 1 a third or more interfaces can be provided.
  • step S0 for example with switching on the electronic devices 1, 1a to 1e connected via the network 8.
  • the electronic device 1 In order to enable a communication according to the CEC standard, the electronic device 1 has to get the logical addresses of all connected further electronic devices 1a to 1e in order to enable a proper communication within the network 8.
  • the electronic device 1 therefore can send polling messages to all logical addresses within the network 8 in order to receive an answer from each further electronic device 1a to 1e reporting the respective CEC logical address. Otherwise each further electronic device 1a to 1e can automatically send a message reporting the logical address to which it is connected after being switched on.
  • an electronic device 1a to 1e is newly connected to the network 8. In this case the newly connected electronic device 1a to 1e will report its logical address to the other devices 1, 1a to 1e connected to the network 8.
  • the electronic device 1 will store the received logical CEC addresses in the storage 5.
  • the electronic device 1 has to link the respective CEC logical addresses to the respective IP addresses within the Ethernet connection.
  • This list of CEC addresses and corresponding IP Ethernet addresses is stored in a database.
  • the electronic device 1 therefore checks if it is possible to get the whole database from a single further electronic device 1a to 1e or if it is necessary to request the Ethernet IP address from each further electronic device 1a to 1e separately.
  • the electronic device 1 therefore in step S3 checks whether a database request is provided.
  • the electronic device 1 in the next step requests the database containing a list of all CEC logical addresses and of all IP addresses from a single further electronic device 1a to 1e. That means that a single further electronic device 1a to 1e holds the whole database comprising the list of CEC and IP addresses and is adapted to transmit the whole list upon request.
  • the electronic device will send a request to each of the further electronic devices 1a to 1e thereby requesting from each further electronic device 1a to 1e the respective IP Ethernet address.
  • a first possibility for requesting the second address is to use the first interface 6.
  • the electronic device 1 hereby uses the first interface 6 and the CEC communication standard for sending a request for the IP addresses.
  • new CEC commands and answers could be adopted.
  • a command "get database” could be adopted.
  • the command "get IP address” could be adopted.
  • the electronic device 1 sends the request for the database to one specific further electronic device in case the electronic device 1 knows that there is a specific further 1a to 1e electronic device 1a to 1e holding the database and being adapted to send the whole database. Otherwise the electronic device 1 will broadcast the request for the database via the network 8 and wait for an answer.
  • a second possibility for requesting the second address is to use the second interface 7.
  • the IP address is requested via an Universal Plug and Play (UPnP) mechanism and the traffic goes over the Ethernet connection, i.e. over the second interface 7.
  • UFP Universal Plug and Play
  • a device description file e.g. a XML file
  • the further electronic device 1a to 1e links its own first address to its own second address and is adapted to send a file comprising both addresses.
  • the electronic device 1 will store the received IP Ethernet addresses together with the logical CEC addresses in order to have a link between the logical CEC addresses and the IP addresses.
  • the electronic device 1 is adapted to look up which IP address belongs to which CEC address and can thereby use the Ethernet connection for CEC features.
  • the electronic device I can use the different addresses for applications. For example at present when using a combined HDMI and CEC connection is was only possible to transmit the HDMI signal into one single direction. Since the present invention now adopts the possibility of additionally using a fast Ethernet connection the HDMI signal can now be sent in both directions over the Ethernet. Further it is possible to transmit commands and data relating to sound or other media related data via the Ethernet connection. This results in a reduction of the cables and connections which are necessary between the different electronic devices 1a to 1e.
  • the electronic device 1 checks if one of the further electronic devices 1a to 1e did not answer upon sending a request or polling message. In case this further electronic device 1 a to 1e did not answer then in the next step S9 the respective further electronic device is deleted from the list stored in the storage 5. Otherwise, if all further electronic 1a to 1e devices keep answering then in the next step S10 the list is kept in unamended form. Additionally, in case a device gets newly connected, then this device after having reported its CEC logical address will be requested to also transmit its IP address and the electronic device 1 will update the list stored in the storage.
  • step S11 ends in step S11 for example with switching off the electronic devices 1, 1a to 1e.
  • one single connector which comprises the cables and connections for the Ethernet connection as well as for the CEC connection.
  • the user is enabled to connect the different electronic devices via one single cable but has the possibility to use a wide variety of communication standards in order to have large possibilities of using his system of electronic devices.
  • each of the further electronic devices la to 1e connected to the network can be adapted to carry out the same steps as the described electronic device 1, so that each of the further electronic devices also holds a list of CEC addresses and associated IP addresses in order to use the Ethernet connection.
